Witness video and chopper video taken at the scene in downtown LA, shows both FBI and HSI agents responding as at least two people were detained outside Ambiance Apparel on Towne Avenue.

A local immigrant rights organization said more than 45 people were detained in the operations, which were described as “random sweeps.”

Federal immigration authorities carried out enforcement activities at several locations in Los Angeles on Friday, with some clashes breaking out as crowds gathered outside a warehouse and other locations across the city to protest the activity.
